One of the earliest patents for a corn cob holder was granted to Mary Donnelly in 1897 for her invention of the Corn-Fork, a corn-holding device that featured a pacifier-shaped handle and three sharp prongs. In 1909, Carl Bomeisler patented a corn holder that looked like a mini sword. In the 1950s, his design morphed into the iconic yellow holders shaped like mini corn cobs that are still used today. In 1977, Larry Riedinger and George Spector created the cornscrew, which featured a corkscrew design. Today, the modified Bomeisler design remains the most popular, but there are many corn cob holders on the market for consumers to choose from.
